title: [Adjuvant treatment after radical prostatectomy in prostatic carcinoma (pT3 or pTxN+): prognostic factors and results].
abstract: Adjuvant therapy after radical prostatectomy should ideally be limited to those patients at greatest risk for cancer recurrence, but identification of these patients remains a challenge. The local control rate in a group of 7494 patients undergoing radical prostatectomy for patients with pT2a disease of 76% is not different to pN+ disease of 80%. 95% of the pT3 patients were pN+ .90% of them received adjuvant treatment but only few patients with organ-confined cancer. A prognostic scoring system was created using the regression coefficients from the Cox multivariate model to classify patients with pathologically organ-confined prostate cancer according to risk of progression. Although tumor volume has traditionally been regarded as the most important prognostic factor in patients with localized prostate cancer, a recent multivariate analysis has shown that tumor volume is not an independent predictor. Moreover, accurate measurement of tumor volume is extremely difficult. Preoperative serum PSA levels, clinical stage, pathological grade and stage, and deoxyribonucleic acid (DNA) ploidy were evaluated by multivariate analysis to determine relative value in predicting treatment failure. Patients with the lowest score had a 92% progression free survival rate at 5 years, compared to only 39% of those with the highest scores. Patients believed to be at higher risk for cancer progression despite having organ confined disease might be targeted for adjuvant therapy and closer surveillance, while those at low risk may be followed less often.
